how to create a normal for 3 nodes

Recommended Posts

Hello Jamie,


To get normal defined by a plane of 3 nodes you can try the below:

proc NormalFrmPlane {n1 n2 n3} {
    set lst_coord1 [lindex [hm_nodevalue $n1] 0];
    set lst_coord2 [lindex [hm_nodevalue $n2] 0];
    set lst_coord3 [lindex [hm_nodevalue $n3] 0];
    set vec1 [::hwat::math::GetVector $lst_coord1 $lst_coord2];
    set vec2 [::hwat::math::GetVector $lst_coord2 $lst_coord3];
    set normal [::hwat::math::VectorCrossProduct $vec1 $vec2];
    return $normal;
